SWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent No. 477,180, dated June 14,1892.

Application filed April 25, 1892. Serial No. 430,560. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. IIUTGHINS, a citizen of the United States,residing at lVorcester, in the county of Vorcester and State ofMassachusetts, have invented certain new and useful Improvements inSwivel- Looms; and I do hereby declare that the following is a full,clear, and exact description thereof, which, in connection with thedrawings making a part of this specification, will enable others skilledin the art to which my invention belongs to make and use the same.

My invention relates to swivel-looms, and more particularly to theswivel-shuttle beam,

or that portion of the swivel-shuttle loom in which are supported theswivel-shuttles and their operating mechanism; and the object of myinvention is to improve upon the construction of the swivel-shuttle beamand to provide independent swivel-shuttle-carrying blocks in which aresupported the swivel-shuttles and pinions for operating the same, whichblocks are adapt-ed to be detached from the swivelshuttle beam properfor the purpose of getting at the swivel-shuttles to change the bobbinsor for any other purpose and to be attached thereto.

A further object of my invention is to improve upon the construction ofthe swivel- 0 shuttle-carrying block as now ordinarily made.

My invention consists in certain novel features of construction of theswivel'shuttle-carrying block and the manner of attaching the same tothe swivel-shuttle beam proper, as

will be hereinafter fully described.

Referring to the drawings, Figure l is a front view, partially brokenaway, of a detached portion of the swivel-shuttle beam of 40 my improvedconstruction; and Fig. 2 is a cross-section on line 2 2,Fig. 1, lookingin the direction of arrow at, same figure.

It will be understood that my improvements in the construction of theswivel-shuttle beam of a swivel-shuttle loom are adapted to be used onswivel-shuttle looms in which more than one set of swivel-shuttles areused, the swivel-shuttles being arranged in rows one back of the otherand extending in a vertical plane. I have shown in the drawings threerows of swivel-shuttles.

In the accompanying drawings, 1 is a portion of the swivel-shuttle beam,which,it will be understood, is supported above the lay of the loom andadapted to be raised or lowered 5 at the proper time to allow the swivelshuttles to operate and weave in the spots in the fabric in connectionwith the ordinary fiy-shnttle mechanism.

2 are the swivel-shuttle racks, supported in grooves in the underside ofthe upper part of the swivel-shuttle beam in the ordinary way andadapted to have a reciprocating motion therein by means of any of thewell-known mechanisms employed in swivel-looms. 6 5

3 is the swivel-shlittle-carrying block, made separate from that portionof the swivel-shuttle beam in which are supported the swivelshuttleracks 2. In the block 3 are supported in this instance two sets ofpinions 4. and 5, arranged one above the other. The upper set of pinions4: is operated by the rack 2, and the lower set of pinions 5 is operatedby the upper set of pinions & and in turn operates the swivel-shuttles6.

I will now describe the construction of the block 3, which supports thepinions and swivelshuttles, as the same forms one of the features of myinvention.

The block 3 is made of four separate pieces or divisions 7, S, 9, and10, (see Fig. 2 the width of which corresponds to the length of theswivel-shuttle. (See Fig. 1.) The four divisions 7, S, 9, and 10 areseparated from each other and held apart to form vertical 8;

spaces for the reception of the pinions and swivel-shuttles by smalltubes orbushings ll, interposed between them, and the bushings llareheld in place by screws or bolts 12, which extend through holes inthe division 7, 8, 9, 0 and 10 and hold the bushings 11 in place, asclearly shown in Fig. 2. The heads of the screws 12 bear on the outersurface of the front division 7, and the screw-threads on their otherends receive nuts 13, which bear on the outer surface of the back piece10. The bushings 11 are held stationary between the divisions 7, 8, 9,and 10 and form distancepieces between the divisions of the block andserve as journals or bearings for, the pinions 4 and 5, which turnfreely and are loose on said bushings 11. The thickness of the pinions 1and 5 is a little less than the length of the bushings 11 between thedivisions 7, 8, 9, and 10, so as to allow the pinions to revolve freelyin the spaces between said divisions. In the block 3 the outer divisions7 and 10 are made a little longer than the intermediate divisions 8 and9 and are notched at their upper ends on their outer surface at 14 toreceive a corresponding tongue or projection 15 on the lower outer edgesof the shuttle-beam 1. (See Fig. 2.)

The lower ends of the divisions 7, 8, 9, and 10 of the block 3 areprovided with tongues or flanges 16, which extend into grooves 17 in theswivel-shuttles 6 in the ordinary way.

It will be understood that the teeth 2' of the racks 2 mesh with theteeth 4: of the pinions 4, and that the teeth 4' of the pinions 4 alsomesh'with the teeth 5 of the pinions 5, which in turn mesh with theteeth 6 on the swivel-shuttle 6.

By means of the notches 1t in the upper outer edges of the block 3 andthe corresponding tongues 15 011 the lower outer edges of theswivel-shuttle beam 1 the block 3 is fitted to the swivel-shuttle beamand is of the same thickness as the swivel-shuttle beam. (See Fig. 2.)

I prefer to attach the block 3 to that portion of the swivel-shuttlebeam which carries the swivel-shuttle racks 2 by the spring hookssecured atits lower end to the central portion of the block 3, at itsfront side, by screws 20 or otherwise and is provided with a bent end orhook 18 at its upper end, which is adapted to extend over and engage theupper front edge of the swivel-shuttle beam. The second spring 19 issecured at its upper end to the back side of the swivel-shuttle beam 1by screws 21 or otherwise andis provided with a bent end or hook 19 atits lower end, which is adapted to extend over and engage the lowerinner edge of the block 3, as clearly shown in Fig. 2.

It will be seen that by bending outwardly thehooked end of either of thesprings 18 and 19 the block 3 may be detached from the swivel-shuttlerail 1 along the line of division 2 and removed for the purpose ofgetting at the swivel-shuttles 6 or for any other purpose.

The advantages of my improved construction of the independentcarrying-blocks or supports for the swivel-shuttles and theiroperating-pinions and the manner of combining the same with theswivel-shu ttle beam will be readily appreciated by those skilled in theart.

The swivel-shuttle block can be quickly and readily made and is easilyput together, as will be seen by referring to the drawings, for it isonly necessary to insert the bushings 11 into the hubs of the pinions 4and 5 and then place the pinions with the bushings between the divisions7, 8, 9, and 10, which have previously had holes bored therein for thereception of the holding bolts or screws 12, and

- then pass the holding-screws 12 through the bushings 11 and bind allthe parts together by the nuts 13. By making the swivel-shuttle blockentirely separate from the swivel-shuttle beam proper and attaching thesame thereto by means of the spring hooks or catches 18 and 19 theswivel-shuttle block can be quickly and readily detached from theswivel-shuttle beam to obtain access to any one of the swivelshuttles inthe block without changing the position of the swivel-shuttle beamproper and without moving any of the other swivelshuttles except thosecontained in the block which is removed.

It will be understood that the details of construction of theswivel-shuttle beam and the swivel-shuttle block maybe variedsomewhatfrom what is shown and described, if
